Angus Gratton eeed037f70 extmod/machine_usb_device: Document xfer_cb result value, add enums.
This callback argument was previously mis-labelled as a boolean,
but it's actually the tusb_xfer_result_t values from TinyUSB.

Jeff Epler 02f2683bfc py/objint_longlong: Fix signed comparison error.
Under `afl-cc` (acting as a wrapper for clang), the following
diagnostic occurs (wrapped for clarity):

    ../../py/objint_longlong.c:232:32: error:
        comparison of integers of different signs:
        'long long' and 'unsigned long' [-Werror,-Wsign-compare]

Add a cast to silence it. The value is known statically to fit inside
`long long`.

Damien George a43a8ac89e py/mpconfig: Automatically configure thumb2 and float emitter features.
Prior to this commit a port would need to manually configure the
`MICROPY_EMIT_THUMB_ARMV7M` and `MICROPY_EMIT_INLINE_THUMB_FLOAT` options,
based on whether the CPU is Thumb2 and whether it has hardware floating
point support (eg Cortex-M0+ vs Cortex-M3 vs Cortex-M4).

This is error prone, for example on stm32:
- `NUCLEO_G0B1RE` (a Cortex-M0+ MCU) had both enabled even though neither
  options work on that target.
- `NUCLEO_L152RE` (a Cortex-M3 MCU) had both enabled but this target does
  not support hardware floating point.

The change here automatically enables the two options based on built-in
compiler macros.

This change is tested on the following boards:
- alif ALIF_ENSEMBLE: both enabled
- rp2 RPI_PICO: both disabled
- rp2 RPI_PICO2: both enabled
- samd SAMD21_XPLAINED_PRO: both disabled
- samd SAMD_GENERIC_D51X20: both enabled
- stm32 NUCLEO_G0B1RE: both disabled
- stm32 NUCLEO_L152RE: only MICROPY_EMIT_THUMB_ARMV7M enabled
- stm32 PYBD_SF6: both enabled
- stm32 PYBV10: both enabled

Properly cast tuple subclasses to the native base class before performing
`__add__` or `__iadd_`.

Jeff Epler 5b127f022e py/modio: Error out on over-long read()/write() in user IO code.
It is a mistake in Python code if the result of readinto()/write()
is more bytes than requested. This can lead to misbehavior
e.g., in mp_stream_rw if the invariant is not respected.

CPython appears to largely ignore the values returned from
readinto()/write(), at least from `print()` & `json.load()`.
Consequently, an expected output file is needed for the
new test.

Closes: #18845

Jeff Epler 5ddc551bc4 py/compile: Reject *arg after keyword argument.
Document this in cpydiff and add a test with expected output
for coverage testing.

As discussed in #11441, the code growth from handling this
case seems to outweigh the benefit of implementing it
properly.

Closes: #11439

Alessandro Gatti b67c55cb4f py/emitinlinethumb: Shrink condition code lookups.
This commit optimises the lookup of opcodes' condition codes, in order
to take up less code than before.

The original data was held in a table containing the condition code
value (an incrementing 0-based integer) and the two condition ASCII
characters.  Given that the condition code value also matches the
entry's index in the table, that can be safely omitted.

This saves 52 bytes when compiled for Thumb.

Alessandro Gatti 1a8c835308 docs/library/machine.Pin: Update pull-up/down constants.
This commit updates the documentation bits for pull-up/pull-down
constants, part of the `machine.Pin` class.

The documentation now mentions port-specific entries into a separate
section, making the only three standard pull-up/pull-down values being
`Pin.PULL_UP`, `Pin.PULL_DOWN`, and `None`.

The compiler flags -ansi -std=c11 were both being passed to g++, causing
weirdness. Removed the -ansi flag entirely, it's superseded by explicitly
setting the standard.

If you enable Actions on your fork of MicroPython then it consistently
fails the Coverage Upload step (unless you set a codecov token in your
fork).  This means you get a failure email each time you push to your own
repo.

This commit fixes that.

Andrew Leech 295df7c0b4 github/workflows: Drop VS2017, use preinstalled v142 toolset for VS2019.
The VS 2017 and VS 2019 MSVC CI jobs have been failing intermittently for
months due to Chocolatey/Microsoft installer infrastructure issues when
downloading old Visual Studio build tools onto windows-latest runners.
These are not code failures - the build tools installation itself is
unreliable (CDN timeouts, corrupt downloads, installer self-update loops).

This removes VS 2017 from the matrix entirely and switches VS 2019 to use
the v142 toolset that's already pre-installed on windows-2022 runners as a
component of VS 2022.  The PlatformToolset is now passed explicitly to
MSBuild for both VS 2019 (v142) and VS 2022 (v143), and the Chocolatey
installation step is removed.

VS 2017 reached end-of-life in 2022, and the v141 toolset is no longer
reliably installable on GitHub-hosted runners (actions/runner-images#9701,
actions/runner-images#12764).  The windows-2019 runner image was removed in
June 2025.  Docker containers are not supported on Windows runners, and the
repo's 10GB Actions cache is already full, so caching the installation
isn't feasible either.  MSVC v143 is binary-compatible back to v141, so the
testing value of v141 was marginal.

The net effect is 16 MSVC jobs (down from 24) with zero installation steps
and hopefully no more flaky failures.

Alessandro Gatti 2f16bf430a esp32/network_wlan: Look up IP addresses for the stations list.
This commit extends the output of `WLAN.status('stations')` to also
include the IP address of WiFi stations connected to the device if in AP
mode.

IP address lookup is currently not available on targets that use hosted
WiFi (eg. ESP32P4), as the hosted API does not yet support performing
the MAC->IP lookup on the WiFi MCU end.

The ESP32 port is brought up to parity with most ports in this regard
(primarily with the ESP8266).  This functionality depends on the DHCP
server provided by ESP-IDF, which is automatically run on the WiFi
interface if the device is put in AP mode.  Currently the ESP32 port
cannot run with said DHCP server disabled, so if a device does not
request a static IP it may either have the wrong IP address returned
(since the DHCP server assigned an address which is then discarded by
the client), or it won't have any (ie. "0.0.0.0").  In the latter case
`None` will be returned as the station's address instead.

This implements #9203.

Alessandro Gatti 024178455d unix/modsocket: Add "sendall" method to socket class.
This commit adds an implementation for "socket.sendall" to the Unix
port.

Right now the implementation is a wrapper over a single "socket.send"
call, since it wasn't possible to let "socket.send" perform a partial
transfer.  With no partial transfers it is not possible to have a
testable implementation following the expected behaviour, so a single
send operation is done and OSErr(EINTR) is raised if a partial transfer
occurs.

The discussion for the issue linked to this PR contains more information
about the efforts made to let partial transfers happen.

This fixes #16803.

This commit extends the parser's behaviour to also recognise constant
integer assignments even when the assignment itself has a type
annotation.

Now declarations like "var: int = const(val)" can be treated as
constants by the compiler and thus be folded in the rest of the program
as it sees fit.  Before this change, that line would generate a variable
creation and its value assignment, without any folding being performed.

This fixes #15608.
